Upgrading Impala

Upgrading Impala involves building or acquiring new Impala-related binaries,
and then restarting Impala services.

Upgrading Impala

Shut down all Impala-related daemons on
all relevant hosts in the cluster:

Stop impalad on each Impala node in your cluster:

$ sudo service impala-server stop

Stop any instances of the state store in your cluster:

$ sudo service impala-state-store stop

Stop any instances of the catalog service in your cluster:

$ sudo service impala-catalog stop

Follow the build procedure in the
README.md file
to produce new Impala binaries.

Replace the binaries for all Impala-related
daemons on all relevant hosts in the cluster.

Check if there are new recommended or required configuration settings to put into place in the
configuration files, typically under /etc/impala/conf. See
Post-Installation Configuration for Impala for settings related to performance and
scalability.

Restart all Impala-related daemons on
all relevant hosts in the cluster:

Restart the Impala state store service on the desired nodes in your cluster. Expect to see a process
named statestored if the service started successfully.
